Title: Self-excited oscillating type semiconductor laser element
Inventor: SUMINO MASAYOSHI
IPC: H01S5/065
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To reduce carrier life of a saturable absorption layer by setting lattice defect density of at least one semiconductor layer having a minimum forbidden band width in a semiconductor layer for constituting the absorption layer to specific multiples of the density of one semiconductor layer for constituting an active layer. SOLUTION: In the case of using a gas source MBE method, when an n-type GaInP well layer of a saturable absorption layer is grown at a lower temperature by 40 deg.C than a growing temperature of an active layer 107 by the same group V/group III ratio as group V/group III ratio at the time of growing a GaInP well layer of the layer 107, lattice defect density of the GaInP well layer of a saturable absorption layer 110 can be set to not less than five times that of the GaInP well layer of the layer 107. When the PL strength is reduced by ten times, carrier life time is decreased by ten times. Hence, when the density is increased by ten times, the carrier lifetime is decreased by ten times. Accordingly, the defect is introduced into the absorption layer, the carrier lifetime of the absorption layer can be reduced.

Title: Image forming device
Inventor: HOSOI ATSUSHI
IPC: G03G15/06
Filed: 1988-12-20
Abstract: PURPOSE:To prevent a picture, formed based on the picture of the leading edge part of an original, from being fogged and omitted by providing a photodetector near an image forming means on the opposite side of the moving direction of the original. CONSTITUTION:When the leading edge part of the original 1 is right above a rod lens array 7, the photodetector 11, provided near the lens array 7 on the opposite side of the moving direction of the original, receives light from the central part of the original 1 when the rod lens array 7 receives light reflected from a white plate 4. Since the photodetector 11 determines the light reflected from the original 1 and alters the bias voltage of a developing unit 9 so as to make a picture lighter, a picture formed based on the white plate 4 is made into a white base. Thus, generation of fog in the leading edge of the picture is prevented and the omission of the picture is also prevented.

Abstract: PURPOSE:To make a CMOS element high in operational speed by a method wherein a p and an n channel FET are formed on an insulating layer selecting a facial index large in a carrier mobility so as to make carriers high in mobility. CONSTITUTION:A SiO2 layer 2 is formed on an n-Si substrate 1 with a facial (110) as an insulating layer through a thermal oxidation and a hole is bored to expose the substrate 1. A poly-Si layer 3 is deposited on the whole face of the substrate 1 by vapor growth. The Si layer is separated to form two regions, where one is a poly-Si layer 3A containing an opening and the other is a poly-Si layer 3B. A CVD-SiO2 layer 4 is formed on the whole face of the substrate 1. The Si layers 3A and 3B are crystallized again to form a re-crystallized Si layers 3AR and 3BR by irradiating laser rays. The CVD-SiO2 layer 4 is removed through a fluoric acid wet etching. A p channel FET is formed on the Si layer 3AR and an n channel FET is constructed on the Si layer 3BR. By these processes, carriers are made high in mobility, so that a CMOS element high in operational speed can be realized.

Title: Input/output controller
Inventor: ISHIDA MASUMI
IPC: G05B23/02
Filed: 1990-11-26
Abstract: PURPOSE:To specify an abnormal input/output circuit without using any special test jig by inputting a signal for testing to input circuits through an output circuit and checking the test signal by a signal processing part. CONSTITUTION:Setting pins are short-circuited normally between A and B under the command of a control part 1a. If abnormality occurs to input and output from and output to an external equipment, the setting pins 10a-10d are short-circuited between B and C. Consequently, the test signal generated by an internal power source E is applied to the input circuits 8a and 8b and the control part 1a outputs an output signal Oa to the output circuit 9a through an output part 7 so as to check the input and output circuits 8a and 9a, thereby making a contact. An input signal Ia can be supplied from a photodiode 8a1 to an input part 6 through a phototransistor 8a2 by the making of the contact and then inputted to the control part 1a. At this time, abnormality of the circuit 8a or circuit 9a is decided unless the control part 1a confirms the input signal. Abnormality of the input circuit 8b and an output circuit 9b is checked similarly.

Title: Process cartridge and electrophotographic image forming device
Inventor: NAKAGAWA TAKAO
IPC: G03G15/08
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent rough toner grains from being generated because a developer is melted/solidified with frictional heating, etc., by forming a hole having a specific slope in a periphery for loosely fitting/supporting the end part of a stirring member and executing sliding in the hole with line contact. SOLUTION: A developing means is provided with the rotatable stirring member 9e for stripping the developer housed in a cartridge frame 12. The hole part 12B1 for loosely fitting/supporting the end part of the stirring member 9e is formed as the hole having a slope of 1 deg. or more with the periphery of the end part of the stirring member 9e. The outer periphery slides while coming into linear contact with the inner periphery of the hole part 12B1, in the longitudinal direction of the stirring member 9e, by the rotation of the toner stirring member 9e by a stirring gear 9m, so that heat and pressure are not exerted on the toner infiltrating the hole part 12B1 to discharge the toner from an opening.  Thus, the sliding of the toner, between the outer periphery of a nondriving side end part 9e2 and the inner periphery of the hole part 12B1, due to the rotation of the toner stirring member 9e can be avoided to prevent the generation of the rough toner grains.
